Thanks Steve do you know if tmpfs gets writen to disk? The Docs I
found said it goes in swap. I ask because I am debugging a program by
writing and erasing alot(read hundreds of thousands) of small
files(less then 15MB). And my laptops harddrive then died, so I want
to avoid any posiablity That Further testing will kill my new drive.
